Abstract: Techniques are provided to drive a normally white or mixed mode LCD with low voltages and low power consumption. A sub-pixel in the LCD may comprise a reflective part and a transmissive part. The cell gap for a liquid crystal layer in the sub-pixel may provide at least a half-wave phase retardation. A driving voltage range with a maximum voltage at a low value may be used to drive the reflective part and the transmissive part of the sub-pixel to various levels of brightness.

Abstract: Techniques are provided for normally black multi-mode LCDs using homogeneously aligned liquid crystal materials which optical birefringence is electrically controllable. A light recycling/redirecting film may be added between a BLU and a nearby polarization layer to recycle backlight from a reflective part of an LCD unit structure into a transmissive part of the same structure to increase the optical output efficiency of the BLU. Electrodes for the transmissive part and the reflective part may be separately driven in various operating modes. Benefits include high transmittance, high reflectance, wide view angles, improved optical recycling efficiency, and low manufacturing costs.

Abstract: Techniques are provided to recycle light from a backlight unit that is otherwise blocked in a reflective part of a pixel in a transflective LCD. The light is redirected into a transmissive part of the pixel and hence enhances light efficiency and luminance of the pixel. The techniques can be used in a transflective LCD that transmits light in a circularly polarized state, or a linearly polarized state.
